Summary:The activity of red blood cell Glucose 6-phosphate dehydrogenase (G6PD) in one hundred and twenty six healthy male individuals who are Nigerians residing in Jos was evaluated. The enzyme activity was determined quantitatively by spectrophotometer assay method. The activity of red cell G6PD enzyme was subnormal in 20% of the population studied. This agrees with previous report of the prevalence of G6PD deficiency in Nigerian males from the Western region of the country which is between 20 and 26%. The proportion of Nigerian males with subnormal G6PD activity is relatively constant irrespective of their geographical location.

Documentation of the transfusion needs of neonatal units is required to guide blood banks in meeting demands. A prospective observational study of newborn transfusions over 35 weeks was conducted. Eighty-four transfusions were conducted in 62 of 377 (16.45%) admitted infants in 35 weeks. Neonatal jaundice (57.2%) and anemia (38.1%) were main indications. In 85.7% cases, blood transfused was < 3 days old. Weight of infants at transfusion was < 2500 g in 51.6% cases. Infants were first transfused at < 7 days in 59.7% cases. Whole blood was used in 64.3% of all cases. Overall transfusion rate was 2.4/week. Neonatal jaundice is the commonest indication for transfusion and whole blood is in greater demand.
